Ok, so nvrbeen needs to get smacked pretty bad:
Professor Hulk
He starts out as a Class 100 level guy, can grow in strength, not fast as Savage, but almost, and the difference, is not big, Professor's only weakness was being a bit less durable, but he could just get pissed off and keep his intelligence and outsmart others.
Hercules
In the IG/IW saga he was the half-god one, it means Thor strength level and immense durability.
Thing
Ok, he was like Class 85/90 at the time, so he's not much of a big gun, you're right on this.
Thanos VS Power Gem users
Do you understand that despite the madness, Thor was fighting Thanos and knowed well who he was fighting, that's why he was so mercyless also, cause even under normal circumstances he knows he''s dealing with major troubles against Thanos.Champion fought Thanos and got pissed off cause found someone able to punch him and make him feeling the punch.
Thanos VS Drax, no power gem, no "Hulk" size one.
The Drax who destroyed a planet while fighting FIST TO FIST with Thanos wasn't even using the gem.Punches that crushes a planet are enough to you?
